Causes of hard disk failures industrial machine and the corresponding protection improvement scheme

Causes of hard disk failure is very much, can be roughly divided into the two factors: one is the quality problem of the hard drive itself, the other - Is the work environment caused as a result of the problem. Hard disk itself quality problem, we can't deeply fastidious, only in the start control system, choose to buy good quality, brand drive, also can use Scandisk, Norton DiskDoctor software such as hard disk surface defect detection. Here we share work environment caused as a result of the problems and the corresponding protection improvement scheme of fault factors, industrial machine work long hours; Protection improvement, from the point of practical experience, a standard month ( 30 days) Restart and finishing a industrial tablet can reduce the risk of hard disk error. Internal fault factors, industrial machine high temperature; Protection to improve, we can simply DIR oneself industrial tablets, to reduce the role of the environment temperature. One, replace the high power CPU, hard disk fan ( Pay attention to the fixed disk fan, should not be installed on the hard drive firmware frame, just in case for fan rotation bring hard disk) To speed up the cooling; Second, inside the chassis mounted to the chassis outside convulsions of the fans, increasing air convection; Three, placed in industrial rack on tablets, installation of small axial flow fan; Fourth, in the control room equipped with air conditioning, in order to reduce the space temperature. Fault factors, environment humidity caused by inappropriate static threats; Protection to improve, to prevent electrostatic threat, industrial tablet we must be good instrument grounding. Worth mentioning is that different industrial tablet grounding and the construction of lightning protection grounding, grounding pole location should be three meters away from the control room, outside under the floor of 1700 mm. Shaking shock failure factors, place; Protection to improve, we as far as possible the all-in-one control in the first place in the far away from the original large work area, workplace restrictions, will be installed with the industrial control cabinet, cabinet put sponge, can buffer objects with small vibration damage. Failure factors, the particulate matter in the air, the industrial environment the body work, accumulated a lot of industrial machine set usually dust, especially in the CPU, power supply, hard disk, such as cooling fans around; Protection to improve the casing leak out strainer gauze, operator training timing blowing dust and regular cleaning work habits. Failure factors, the electricity power supply voltage fluctuation, easy to; Protection to improve, the regulated power supply and UPS uninterruptible power supply protection
